Carbonization and Preparation of Nitrogen-Doped Porous Carbon Materials from Zn-MOF and Its Applications

Abstract

Nitrogen-doped porous carbon (NPC) materials were successfully synthesized via a Zn-containing metal-organic framework (Zn-MOF). The resulting NPC materials are characterized using various physicochemical techniques which indicated that the NPC materials obtained at different carbonization temperatures exhibited different properties. Pristine MOF morphology and pore size are retained after carbonization at particular temperatures (600 °C-NPC600 and 800 °C-NPC800). NPC800 material shows an excellent surface area 1192 m2/g, total pore volume 0.92 cm3/g and displays a higher CO2 uptake 4.71 mmol/g at 273 k and 1 bar. Furthermore, NPC600 material displays good electrochemical sensing towards H2O2. Under optimized conditions, our sensor exhibited a wide linearity range between 100 µM and 10 mM with a detection limit of 27.5 µM.

Porous Ladder Polymer Networks

“…[151][152][153][154][155] Among these reported examples, several were synthesized in a bottom-up approach or derived from bottom-up synthesized metalorganic frameworks. [156][157][158][159] Most of these materials were constructed in a stepwise manner, with high-temperature annealing required for the ladderization/graphitization step. Due to complicated reaction pathways during pyrolysis, the exact chemical constitutions of the backbones were usually not clearly characterized.…”
